Answer:
Explanation:
The equivalent of Newton's second law for rotational motions is:
where
is the net torque applied to the object
I is the moment of inertia
is the angular acceleration
In this problem we have:
(net torque, with a negative sign since it is a friction torque, so it acts in the opposite direction as the motion)
is the moment of inertia
Solving for , we find the angular acceleration:
Answer:
Final velocity, v = 0.28 m/s
Explanation:
Given that,
Mass of the model,
Speed of the model,
Mass of another model,
Initial speed of another model,
To find,
Final velocity
Solution,
Let V is the final velocity. As both being soft clay, they naturally stick together. It is a case of inelastic collision. Using the conservation of linear momentum to find it as :
V = 0.28 m/s
So, their final velocity is 0.28 m/s. Hence, this is the required solution.
